FURNACE FOR GASIFYING COAL.

Specification of Letters Patent.

Patented May 18, 1909.

Application mea January 25, 190s. Serin No. 412,650.

r1o all whom it may concern:

Be it known that I, HANS ltins, e citizen of the Empire of Germany, residing at Munich, Germany, have invented certain new anduseful Im rovements in Furnaces for Gasilying Cos s, Roasting Orcs, und the- Like, ci which the following is a. full, clear, and exact description.

This invention relates to furnaces s ecially suitable for the manufacture of coal)gas of theI tfpe having horizontally or obliquely er rang retort chambers adopted to contain the material. to be treated.

The present furnace is distinguished from similar furnaces hitherto known by the Inode of su porting the bottom Walls of the retort cham ers and by the arrangement of the llues or conduits for the heating gases and. the combustion air.

A construction of furnace is illustrated in the accompanying drawings, in which,

Figure l is a vertical lon itudinal section. ofthe furnace on line 1-1 Fi 2, Fig. 2 is a. 'vertical section on line 2-2 o Fig. 1 Fig. Slis a vertical section on line 3-3 of Fig. 1.

As will be seen from the drawings, the retort chambers o which are arranged side by side (three are shown in the example illus-A trated) are separ ted 'from each other by the vertical lues or' enduits c and d, and from the lateritl wallsf and g of the furnace, by

the vertical llues b and e. The fines b and o and d andro are connected together at the top' by transverse roof conduits o', o respecM tively. The lateral walls of the chambers a rest upon laterally projectin bottom walls or stones h carried by vertice pillars 'iy which preferably extend down to the foundations of thg furn so that the Weight of the chambers ay and of their charge is transmitted direct to the foundations.

Below the bottom walls h supporting the chambers a on the pillars 'i are arranged con duits 'In for the heating gases separated by a partition n from air conduits The pertition n terminates immediately below thr rejecting {,ortion o'r' the bottom walls 1i. onsequent jf the combustionol" the hosting; gases takes place in the space laterally lim ted by the bottom well h above the free end o f the partition n, so that at that point is sitdated the hottest combustion zonejhe heat of Whicliis transmitted by thebottom walls l ln that 71r to the bottom of the ch snlbcrsw. Way the bottoms of the chambers e are 'heated to a sullicient extent without it boing necessary to arrange heating conduits in them which greatly affect the durability ol' the chambers. Moreover, owing to the con1- bustion of the heatingr gases takingr place in the space between the bottom Walls h, thel lateral walls of the chambers o are less damaged, forthe bottom series of bricks constitutinnr the lateral walls of tho chambers ere already outside the hottest combustion zone.v The bottom walls la, themselves are made sufllciontly strong and durable to resist the high temperatures to which they are subjected.

Air enters the lower portion of' the regenerster q through the conduit p and after traveling in zie-zag fashion through thc hori zontal channels r it rises through the channel s into the channels k terminating above par titions n. During its passage through the regenerator, the nir is preheated by the com-- bustion gases which travel downward, that is, in s, direction opposite to that of thenir, in channels t surrounding the air channels r. These combustion gases then pass in contact with the Water trough w and lesve the regenerator at u. The combustion gases travel from the generator v through sn upright channel :c to the heating channels m arranged adjacent to the air channel k. The preheated air is adlnixed to these combustion gases directly above the upper edges of the partitions n, that is to say, in the lower portion of the channels c, d which is bounds by the project-m; surfaces z of the retort bottoms h. Per ect combustion is thus secured, und the hot gases poss upward i'n the channels c, d, oil tward in the transverse channels o', oz over the tops of the outer chambers o, sind final Y downward to the regenerator q throught. c channels b, e which communicate with the channels t.

Constructionrd details of the furnace d e- There and the like, comprising a lurality of spaced retort's arranged side by si( e, walls surround-- retorts, t e op using walls of adjacent sup pox-ts flaring ownwardly, so as to ferm a chamber which contracts upwardly, a. )an tition located in faid chamber, and con uits for supplying nir and gas respectively located on opposite sides of said partition and lead- I0 in into Raid chamber.
